Uracanthus punctulatus   , sp. nov.

(Figs 34, 72, 101)


Male. Body length, 28.03–39.96 mm; width, 5.19–7.83 mm.

Colour (Fig. 34). Body blackish brown, covered with dense and thick pale or pale yellow pubescence; pronotal disc with a large longitudinal glabrous area, wider at posterior edge and becoming slightly narrower at anterior edge; punctures on basal half of elytra more or less exposed, giving an appearance of a number of small blackish dots in pubescence on basal elytra.

Head. Postclypeus subtriangular, slightly convex, sparsely and coarsely punctate; frontoclypeal suture wide and deep in middle; distance between lower lobes of eyes 1.75–2 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 0.7–0.85 × as long as distance between eyes on ventral side; genal length 0.8–0.85 × as long as head width immediately below eyes. Antennae shorter than body, segments 4–10 flattened and produced on one side at apex.

Thorax and abdomen. Pronotum 1.18–1.39 × as long as width, side rounded with a feeble process; posterior margin 1.24–1.46 × as wide as anterior margin; pronotal disc binodulose in middle area, with distinct transverse rugae throughout. Scutellum semicircular, with sparse pubescence. Elytra 4.45–4.83 x as long as prothorax and 3.67–4.01 × as long as shoulder width; basal 2/3 of elytra with coarse punctures; apex more or less truncate with 2 sharp spines. Apex of terminal sternite truncate or slightly emarginate.

Male terminalia. Apex of ventral and dorsal median lobes rounded; ventral lobe shorter than dorsal lobe; unspined region of internal sac very short: spined region divided into 2 sections: first section with dense scalelike processes near base and dense large and long simple spines in most part; second section with fairly dense multi-branched spines ( Fig. 72a). Eighth sternite obliquely truncate at sides, strongly emarginate at apex, with long and fairly long setae arising terminally ( Fig. 72b). Eighth tergite more or less truncate and slightly emarginate at apex ( Fig. 72c). Paramere short, 2.0–2.3 × as long as wide, cylindrical in shape, apex rounded with long and short setae ( Fig. 72d).

Female. Body length, 35.41–37.56 mm; width, 7.14–7.32 mm

Body more robust and broader; antennae and legs shorter; elytra 3.61–3.82 × as long as shoulder width and 4.23–4.79 × as long as prothorax; apex of terminal sternite truncate.

Ovipositor and spermatheca. Ovipositor short; styli arising terminally with sparse long and short hairs ( Fig. 72e). Spermatheca slightly curved; spermathecal gland arising at base ( Fig. 72f).

Distribution Northeastern New South Wales and southeastern Queensland ( Fig. 101).

Biology Hosts are unknown. Adults were collected during October–December.


This species was wrongly identified as females of U. insignis   by previous workers. It resembles U. insignis   but differs in having a body covered with uniform pubescence without white pubescent lines on the pronotal disc and the elytral suture not glabrous.
